HLL type elastic pin coupling with brake wheel

The material of the elastic element (column pin) is generally selected from nylon, which has the ability to slightly compensate for the deviation of the two axes. The elastic part is sheared when working, and the working reliability is extremely poor. It is only suitable for the medium-speed transmission shaft system with very low requirements, not applicable For working conditions that require high working reliability.

  HLL type with brake wheelElastic pin couplingIt has been listed as standard GB5014-85, which is suitable for all kinds of transmission shafts that mechanically connect two coaxial lines, and is usually used for frequent high and low speed motions.The working temperature is -20~+80℃; the nominal torque of transmission is 40~20000N.m.The elastic pin coupling has a large structure, simple and reasonable, easy to maintain, symmetrical and interchangeable on both sides, long life, allowing large axial movement, and has the properties of cushioning, shock absorption, and wear resistance. Shaft hole types are available Cylindrical (Y), conical (Z) and short cylindrical (J).The shaft hole and keyway are processed in accordance with the standard GB3852-83 "Coupling shaft column and keyway form and size".The semi-coupling is made of precision casting, cast iron HT20-40, cast steel ZG35Ⅱ, the shaft hole and keyway are made of drawing, and the pin is made of MC nylon b.
  The elastic pin coupling is a pin made of a number of non-metallic elastic materials, which is placed in the flange hole of the two coupling halves, and the two coupling halves are connected by the pin. The coupling structure is simple and easy It is more convenient to manufacture, assemble, disassemble and replace the elastic element, without moving the two halves of the coupling.The material of the elastic element (column pin) is generally nylon, which has the ability to compensate the deviation of the two axes in a small amount. The elastic part is sheared when working, and the working reliability is extremely poor. It is only suitable for the medium-speed transmission shaft system with very low requirements, not applicable For working conditions that require high working reliability.
